A process flow diagram describing the construction of a structure chart by a so-called Subject Matter Experts (SME). [2]According to Wolber (2009), "a structure chart can be developed starting with the creating of a structure, which places the root of an upside-down tree which forms the structure chart.
The Decorator Pattern (or an implementation of this design pattern in Python - as the above example) should not be confused with Python Decorators, a language feature of Python. They are different things. Second to the Python Wiki: The Decorator Pattern is a pattern described in the Design Patterns Book.
The C4 model relies at this level on existing notations such as Unified Modelling Language (UML), Entity Relation Diagrams (ERD) or diagrams generated by Integrated Development Environments (IDE). For level 1 to 3, the C4 model uses 5 basic diagramming elements: persons, software systems, containers, components and relationships.
Primary Concern: It is easy to be too detailed by including many different needs in a single diagram. This should be avoided. It is better to draw multiple diagrams, one for each viewpoint, than to draw a 'mega diagram' that is extremely rich in content. Remember this: when building houses, the architect delivers many different diagrams.
Since structure diagrams represent the structure, they are used extensively in documenting the software architecture of software systems. For example, the component diagram describes how a software system is split up into components and shows the dependencies among these components.
One use of this pattern is during software rewrites. Code can be divided into many small sections, wrapped with the strangler fig pattern, then that section of old code can be swapped out with new code before moving on to the next section. This is less risky and more incremental than swapping out the entire piece of software. [1]
A class diagram exemplifying the singleton pattern. In object-oriented programming, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance. It is one of the well-known "Gang of Four" design patterns, which describe how to solve recurring problems in object-oriented software. [1]
These values, used by the pattern's author to determine which solution is "best", must also be documented within the pattern. Pattern documentation should also explain when it is applicable. Since two houses may be very different from one another, a design pattern for houses must be broad enough to apply to both of them, but not so vague that ...
